JAMES MACPHAIL, OF ROCKFORD, ILLINOIS.

HARROW.

SPECIFICATION forming part of Letters Patent No. 445,587, dated February 3, 1891.

Application filed July 25, 1890.

To all whom it may concern:

Be it known that I, J AMES MAOPHAIL, a citizen of the United States, residing at Rockford, in. the county of innebago and State of Illinois, have invented certain new and useful Improvements in Ilarrows, of which the following is a specification.

The object of my invention is to provide improved knockdown connections between the tilting beam and tiltiug'beam posts of lever-barrows; and it consists of certain new and useful features of construction and combinations of parts hereinafter described, and specifically pointed out in the claims.

Referring to the accompanying drawings, which form a part of this specificatiomEigu re 1 is an isometric view of a section of a lever- 2 and '3 are like views in detail of devices for connecting the tilting beam with the tiltingbeam posts. Fig. I is a back side view of the segment-rack seen in Fig. 1, showing the eonnection of the combined tilting-beam post Like letters of reference indicate corresponding parts throughout the several views.

A are barrow-beams, preferably cylindrical and tubular in form, provided with teeth A, inserted through holes therein.

B are cross-beams. Bare hangers secured to and depending therefrom.

B are circular openings in the hangers B, through which the beams A are inserted and wherein they may be oscillated.

G is a tilting beam, having circular openings O therein provided with lateral slots 0 D are tilting-beam posts, having horizontal stud-journals D projecting therefrom and adapted to be inserted through the circular openings 0 in the tilting beam, and provided at their free ends with laterally-projecting lugs D for retaining the stud-journals therein.

E is a segment-rack secured to the rear end of the tilting beam 0.

E is a tiltinglever secured to the produced end D of the rear tilting-beam post by means of the bolt Serial No. 359,942. (No model.)

E is a'detent for connecting the tilting lever E with the segment-rack E by. engaging the peripheral slots E therein.

To disengage the tilting beam C from the posts D, take out the bolt E and remove the lever E, tilt the barrow-section backward, the points of its teeth being to the front, until the tilting beam rests on the beams A. The lugs D will then be opposite the slots 0 and the stud-journals D can be withdrawn from the openings C therein. Obviously a reversal of the operations just detailed would restore the tilting beam to the position shown in Fig. 1. The tilting beam cannot be tilted forward far enough to allow the stud-journals to be Withdrawn therefrom.

I claim 1. In combination in a lever-barrow, the tilting beam having circular openings therein provided with lateral slots, and the tiltingbeam posts having horizontal studjournals projecting therefrom and adapted to be inserted through the circular openings in the tilting beam, and provided at their free ends with laterally-projecting lugs for retaining the stud-journals therein, substantially as and for the purpose specified.

2. In combination in a lever-barrow, the barrow-beams, the cross-beams, the hangers secured to and depending from the crossbeams and having circular openings therein, through which the barrow-beams are inserted and wherein they may be oscillated, the tilting beam having circular openings therein provided with lateral slots, and the tiltingbeam posts having horizontal stud-journals projecting therefrom and adapted to be inserted through the circular openings in the tilting beam, and provided at their free ends.

with laterally-projecting lugs for retaining the stud-journals therein, substantially as and for the purpose specified.

JAMES MACPI-IAIL.
